WAGON-REACH COUPLING.

SPECIFICATION forming part of Letters Patent No. 259,731, dated June 20, 1882.

I Application filed April 5, 1880. (Nomodeh) To all whom it may concern:

Be it known that I, THOMAS C. TnoMPsoN, a citizen of the United States, residing at Baldwin, in the county of St. Croix and State of Wisconsin, have invented certain new and useful Improvements in Wagon-Reach Couplings; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to improvements in the draft-couplings of wagons, and its object is to increase the strength and durability of, hounds and wagon-reach at the points of greatest wear and strain.

In the accompanying drawings, Figure 1 represents a top plan view of wagon hounds and reach provided with my attachments Fig. 2, a sectional view taken longitudinally of the same; Fig. 3, a perspective view of the screw-bolt which holds the reach in place; and Fig, 4, a perspective view of the nut which, in combination with the screw-bolt, keeps the wagon-reach firmly in place.

Like letters refer to similar parts in the several drawings.

A is a strong flat metal plate fitting the upper surface of the wagon-hounds.

B is a similar plate fitting the lower surface of the hounds.

Screw-bolts a. a, passing through plates and hounds, pin them all firmly together, and ob-' holds the reach in the socket of the hounds and enables the draft end of the reach to he lengthened or shortened, as the occasion may require, the eye d admitting a lever-bar in tightening or loosening the screw-bolt.

E is a flat nut, with eye e in the center to admit the screw-bolt, and with dogs e e at two opposite sides. This nut'fits loosely into a rectangular orifice cut in the under plate, B, and the dogs 6 6 rest in sockets b b, which are turned in the said plate, by which means said nut E is prevented from dropping out of place whenever the screw-bolt is withdrawn to allow a readjustment of the 'wagonreach in the hound-socket.

The nut E has a screw-thread cut inside and around its center eye, 6, to fit the screw-bolt D, so that'whenever the latter is revolved downwardly through and below the wagonreach the nut E (being flat on its upper surface) is pressed and held tightly against the flat under surface of the reach. Whenever the wear and strain on the reach loosens the pressure of;thewnut upwardly against the un-' der surface of the reach, a downward turn of the screw-bolt will tighten it again. In this way the loose rattling play of a worn or thin or large-eyed reach is prevented and the friction of parts and danger of breakage materially reduced.

Having thus described my invention, what I claim as new and useful, and desire to secure
